Figure 4.

Female-biased expression of miRNA expressed from the non-recombining region of the X chromosome (linkage group 19). Black circles indicate small RNAs on the pseudoautosomal region, whereas white circles indicate small RNAs from the X-specific region. A small RNA, for which it was not clear whether the RNA was located on the pseudoautosomal or X-specific region, is indicated by a grey circle. For statistical analysis, the grey circle was excluded. Data from the Japan Sea and Pacific Ocean fish were pooled. Because the order of the LG19 sequence assembly on the ensembl is inverted after 3.822 Mbp, physical locations on LG19 followed [62]. Error bars indicate S.E.
